About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30
The AirTAC SAIJ80X100-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 2513N of push force at 0.5MPa and provides a usable travel window of 70 to 100mm, letting you trim up to 30mm off the nominal stroke. This built-in adjuster allows precise end-position tuning at commissioning without swapping out the physical cylinder.
The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It uses a G3/8 port and a 25mm carbon steel rod with an M20x1.5 thread, providing robust resistance to side loading. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30 Is Used
Machine Setup & Changeover
Fine-tune the retract end position during commissioning or product changeovers without adding external stops or replacing the cylinder.
Variable End Stops
Dial in the exact 70 to 100mm travel window needed for diverting or positioning varying package sizes on a packaging line.
Assembly Pressing
Leverage the 2513N push force at 0.5MPa for pressing components, using the rear screw to precisely limit travel and prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30 the Right Cylinder?
Choose this 80mm bore when your application requires higher thrust than the 63mm bore (which offers 1559N push at 0.5MPa) but does not need the full 3927N push force of the 100mm version. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers, avoiding the need to stock multiple fixed-length SAI cylinders. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as this cylinder lacks a locking mechanism.
To match this ISO 15552 replacement exactly, specify the 80mm bore, 100mm stroke, 30mm adjustment range, PT tapered port thread, standard carbon steel rod, and no magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-30 FAQ
The SAIJ80X100-30 features a rear adjusting screw that acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30mm. This creates a usable travel window of 70 to 100mm. The adjuster only sets the travel end and does not lock the position without live air pressure.
At 0.5MPa, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. It can deliver up to 4523N of push force at its maximum operating pressure of 0.9MPa.
